At a race car driving event, a staff member notices that the skid marks left by the race car are 10.99 m long as it comes to a stop. The very experienced staff member knows that the
deceleration of a car when skidding is -42.61 m/s2. What can the staff member estimate for
the original speed of the race car if it came to a stop during the skid?

Asmall 21 kilogram canoe is floating downriver at a speed of 1 m/s. what is the canoe's kinetic energy?

10. the kinetic theory of matter states that atomic particles will move if the temperature is above the freezing temperature of water atomic particles bounce off each other one time in their life atomic particles are constantly bumping off each other because particles are in direct contact with each other at all times all matter is made up of atomic particles which are in constant random motion

Which statements describe how a machine can make work easier? check all that apply. it can put out more force than the input force by decreasing the distance through which force is applied. it can increase the amount of work performed if the output force is in the same direction as the input force. it can apply a force to an object in a different direction than the force applied to the machine. it can increase the distance through which a force acts by exerting less force than was used on it. it can exert a greater force through a greater distance than the force used on the machine.
